Moving to her own cot/sleep training

Me

For the past 2 days we have been sleep training our 5.5 month old and she’s taken to it extremely well so we decided to push our luck and put her in her own room for the first time. To my shock she slept 8pm-5:30am with not a sound from her! I was wide awake from 2am-4am waiting for her to wake as that’s the usual time she starts to fuss. But nothing! This must be a dream!
